Belden 179DT Digital Video Cable (RG179) 1000ft - Gray

To comfortably support today's broadcast technology, especially HDTV, mobile television broadcast trucks are densely packed with equipment and over-the-road axle weight requirements have become a real concern. To help lighten the trucks load, lessen the amount of space needed, and to improve air-conditioning air flow and gas mileage, Belden offers Brilliance DigiTruck 179DT lightweight RG-179 Type 75-ohm coaxial cable. This new coax weighs 7.25 pounds per 1,000 feet and has a guaranteed return loss of 21dB (minimum) and is sweep tested to 3 GHz.

This mimics the return loss performance of Belden1s most popular Brilliance precision video cables, providing 6dB of RL headroom against the SMPTE 292M specification. 179DT features a highly crush-resistant, foamed high-density polyethylene (FHDPE) dielectric to help ensure the durability of the cable a particularly important characteristic for use on television broadcast trucks.
